Towards Optical Camera Communications Using a Shape-tailored Illuminating Optical Fiber

We have recently presented a novel concept of optical camera communications (OCC) based on illuminating optical fibers (IOF) as transmitter (Tx). In this paper, we further investigate this concept of IOF-based OCC system by replacing a straight IOF by an L-shaped IOF as the transmitter. An intensity modulated light from a white light emitting diode in the on-off keying format at frequencies of 1800 and 2400Hz is launched into the IOF. We experimentally investigate the impact of IOF bending as well as horizontal and vertical orientations of camera-based receiver on the performance of the IOF-based OCC system. The results depict 100% success of reception is achieved over a transmission distance of 50cm for the IOF bending angle in the range of 0 to 90°, and horizontal and vertical orientations of the camera.
